If we're not imposing sanctions on them because of their nuclear weapons program then why the heck are we? Because they're a backward Islamic country that murdered and dismembered a Washington Post journalist in Istanbul? Because they're where 15 of the 19 9/11 bombers were from? Because they're the home and sponsor of the Wahabi sect of the Muslim religion responsible for the last majority of Muslim terror attacks? Because they deny Israel's right to exist? Oh, sorry, I got mixed up with our "ally" Saudi Arabia.
You can't have a well meaning intelligent discussion on Iran if you pretend that the majority of the U.S. concern around Iran isn't around thier nuclear program, sorry that's just not intellectually honest.
Iran has literally been under sanctions since the revolution 40 years ago. That's a pretty good definition for the status quo. It hasn't resulted in much in the way of positive outcomes and there isn't any indication that this time will be any different?
You are wildly misinterpreting my response out of context. I was simply stating that I could find no UN or IAEA supporting information that there was a direct causal relationship between external sanctions and a nuclear armed Iran. I literally could find no authorship that made the case that sanctions spurred development of an Iranian nuclear weapon. For that matter - there was plenty of scientific opinion that Iran does NOT to date possess a nuclear weapon.
